Abstract

We have carried out a systematic study of the effect of microtaper diameter on the spectral characteristics of bottle microresonators. By increasing the microtaper-diameter (D_t) from 2μm to 10μm results in progressively cleaner spectra. The transmission depth at resonance varies from ~15dB (@D_t=2μm) to >3dB (@D_t=10μm). The loaded Q factors were measured to be >10⁺⁶ in all cases. However, with microtaper D_t=10μm clearly-resolved single resonance peaks could be observed and free-spectral ranges could be easily identified. At some transmission resonances, we have observed LP₀₁→LP₁₁ mode transformation at the excitation microtaper waist, for the first time, as the resonance is scanned.
